v 'In connection with cooling bank plants with several delivery channels the leading over of bars onto the cooling bank causes certain inconvenience. Thisis due tothe fact that the bars arelead in groups over an inclined chute" onto the cooling bank. Thereby the bars easily become intermingled pell-mell, this being favoured further bythe circumstance that on account of the diiference'in temperature of the bars during the cooling down period the construction is not uniform in respect to the several bars.

In order to overcome this disadvantage, according to the invention, the bars, which have been deposited in the pockets of the several delivery devices, are lifted out of these pockets separately and independently of one another, for which purpose a lifting device is used that is provided with fingers which on ascending lift the bars out of the pockets and subsequently pass them on to the cooling bank.

Such a device is shown in the accompanying diagrammatic drawings in use in connection with a cooling bank, the delivery devices, and the corresponding pockets of such devices being arranged above one another. The delivery channels proper are not shown in the drawings as their form is of no consequence to the invention.

Fig. 1 is a side-view of the device,

Fig. 2 is a corresponding front-view,

Fig. 3 is a partial plan corresponding to Fig. 2.

The numeral 1 in the drawings designates delivery devices provided with pockets receiving the rolled bars from a suitable source. The rods 2, mounted adjacent to the delivery devices, are

35 adapted to move vertically up and down and are provided with lifting fingers 3 and receiving members 4;, the'rods in question being connected to one another by a transverse girder 5 and being rotatable about their axes. The rotary movement is effected by means of a plurality of rotatable arms 6 which are secured upon pivot pins 7 rotatably mounted on bearing brackets on the girder 5.

Arms 8 which are also secured to the pivot pins 7 are connected by means of links 9 to certain of the cranks 10 which are mounted on the lower ends of the rods 2 (see Fig. 2). The cranks 10 of all the rods 2 are connected to one another by a rod 10a in such a manner that on a rocking movement of the arms 8 the several rods 2 are partially rotated uniformly.

, The said rocking movement of the arms 8 is effected by the striking of the arms 6 against fixedstops 11 and 12.

The transverse girder 5 is engaged at intervals by chains 13, each of which is led around a These chains 13 carry counter weights 16.

The shaft 15 'is driven bya motor (notshown) When the rolled bars which have been deposited in the pockets of thedelivery devicesnl are sprocket-wheel 14 mounted ona common shaft to be lifted therefrom by the lifting fingers 3, the

the arms 6 come into contact with the fixed stops 11, whereby all the rods 2 are turned out of the range of the pockets of the delivery devices 1. The rods 2 are then lowered, depositing at the same time the group of rolled bars supported by them upon the train of rollers designated by the reference 17.

As will be seen from Fig. 3 the lifting out fingers 3 are of an angular form and extend at an acute angle to the direction of movement of the oncoming rolled bars, so that any rolled bar arriving in the pockets of the delivery device 1 while the coacting fingers 3 are in obstructing position is deflected laterally.

The position of the fingers 3 and the adjoining receiving members 4 after rotation into the delivery position is indicated in Fig. 3 by dotted lines.

Having described my invention and how same operates, I claim as new and desire to secure by Letters Patent:

terial, provided with delivery devices for the rolled bars, a plurality of bar lifting members, each comprising a finger carried by a pivotal spindle, a common carrier for the said lifting members, in

which carrier the said spindles are rotatably mounted, means for lifting and lowering the carrier with the said lifting members to cause the latter to lift bars from the delivery devices and deposit them upon the cooling bank, the said lift- .90 1. A cooling bank for rolled bars and like maing members passing through recesses in the said delivery devices, stops positioned at the respective ends of the travel of the carrier, and tripping gear co-operating with the said stops partially to rotate the lifting members out of the range of the delivery devices at the upper limit of travel of the said carrier.

2. A cooling bank according to claim 1, wherein the means for lifting and lowering the carrier comprise an oscillatory spindle, driven members carried by said oscillatory spindle, and flexible elements engaged by said driven members and connected respectively to the said carrier and to counterweights.

3. A cooling bank according to claim 1, having cranks upon the said pivotal spindles, a coupling member coupling the said cranks, an operating spindle transversely disposed to the said coupling member, and arms carried by the said transversely disposed spindle, one of said arms being linked to the coupled cranks and the other of the said arms engaging the stops.

4. A cooling bank according to claim 1, wherein the delivery devices are provided with pockets and recesses in the edges of the pockets which are inclined to the length of the rolled bars resting in the pockets and the lifting members in the rising movement are also inclined to the direction of the said rolled bars in passing through the said recesses.

5. A cooling bank for rolled bars and like material provided with delivery devices for the rolled bars, lifting. members positioned adjacent the said delivery devices, and a rising and falling carrier upon which the said lifting members are pivotally mounted, the said delivery devices being provided with recesses to permit the passage of the lifting members in the rising movement of the carrier and the lifting members being adapted to be rotated out of range of the delivery devices in the falling movement of the carrier.

6. A cooling bank for rolled bars and like material provided with delivery devices having pockets to receive the rolled bars, lifting members p0- sitioned adjacent the said pockets, and a rising and falling carrier upon which the said lifting members are pivotally mounted, the said pockets being provided with recesses to permit the passage of the lifting members in the rising movement of the carrier, the lifting members being adapted to be rotated out of range of the pockets in the falling movement of the carrier, and means for lifting and lowering the said carrier to move the said lifting members relatively to the said pockets from which the bars are removed to be deposited upon the cooling bank.

7. A cooling bank according to claim 6, wherein the lifting members are provided with fingers which in the upward movement of the lifting members pass the pockets in a relative disposition enabling them to lift from the pockets bars resting therein, pivotal spindles upon which the fingers are transversely inclined and bar stops at the lower ends of the said fingers.
